Alexa says hello and doesn't answer

Alsa report log: https://pastebin.com/M3zCP6V8

Description of problem: My usb mic won't work, infact when I try the record test, #(arecord -f S16_LE -r 16000 -D your_input_device test.wav) I get:

"ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) Unknown PCM your_input_device
arecord: main:788: audio open error: No such file or directory"

Furthermore I get a lot of ALSA errors when I check for the AlexaPi status:

I tried with another command:

/opt/AlexaPi/src/main.py

and result is.

[WeirdlyChosen]

I too have this problem. Expected: AlexaPi says hello, then responding to my voice

Problem-relevant config.yaml entries: input_device: ""

playback_handler: "vlc"

output: "" output device: "magicmirror" //this is default from installation output_device: "default"

Steps to reproduce:

1. Install AlexaPi
2. set up system wide pulse audio using this guide
3. AlexaPi failed to start after reboot
4. change config.yaml to be written above Traceback (if applicable):

Additional info: Installed magicmirror before installing AlexaPi AlexaPi working normally after installing and starting manually does not stop AlexaPi while Changing to system wide PulseAudio

@WeirdlyChosen I don't know how works MM but I think you also have to setup your audio devices.

@best303 you have to setup your audio PCMs: List them with aplay -L and change it in the config:

output: "alsa"
output_device: "plughw:YOURDEVICE"

[ZmeiGorynych]

@EmerickH Thanks! Just ran into the same issue - which config is it that I should change?

[jacobkaufman]

You can set your alsa devices in /etc/asound.conf for system-wide or ~/.asoundrc for individual user. If the file doesn't exist you have to create it. If you have a separate mic and speaker then they will be different cards. On the Raspberry Pi my Speaker Bonnet is card0 and my USB mic is card1.
